The production line is designed for 3-5 gallon barreled drinking water, with different capacity QGF-100, QGF-240, QGF-300, QGF-450, QGF-900, QGF-1200 for optional. It combined bottle washing, filling capping in one unit. In order to achieve the purpose of washing and sterilizing, the washing machine uses multi-washing liquid spray and thimerosal spray.
